Idatha yobuthi
Ubuthi obukhulu:

I-LD50 yomlomo: 783mg/kg (ingulube ye-Guinea)

800 mg/kg(imisipha)

832 mg/kg(igundane)

Imiphumela eyinhloko yokucasuka:

Esikhumbeni: Okucasula isikhumba kanye nolwelwesi lwamafinyila.

Ngaphezu kwamehlo: umphumela wokucasuka.

Ukuzwela: Akukho miphumela eyaziwayo yokuzwela.

Idatha yezemvelo
Inothi lengubo

Izinga 1 lengozi yamanzi (Umthetho WaseJalimane) (ukuzihlola ngokwakho ohlwini) Lesi sici siyingozi kancane emanzini.

Ungavumeli inani elikhulu lomkhiqizo elingaxutshiwe noma ukuthintana namanzi angaphansi komhlaba, imisele yamanzi noma izinhlelo zokuhambisa indle.

Ungalahli izinto endaweni ezungezile ngaphandle kwemvume kahulumeni.

Imvelo nokuzinza
Inobuthi obuphakathi nendawo, iyacasula isikhumba kanye nolwelwesi lwamafinyila. Umjovo wegundane ongaphansi kwesikhumba LD50:376mg/kg. Imishini yokusabela kufanele ingangeni moya, futhi i-carboxylation reactor kumele ihlangabezane nezindinganiso zokucindezela. Abasebenzi kufanele bagqoke imaski yokuzivikela kanye neminye imishini yokuzivikela, futhi bagcine umoya omuhle endaweni yokusebenzela.

Indlela yokugcina
Lo mkhiqizo kufanele uvalwe futhi ugcinwe kude nokukhanya.

Sebenzisa
Izithako zokudaya. Zisetshenziselwa ukuhlanganisa i-Naphthol AS nezinye izinhlobo ze-Naphthol, njenge-Naphthol AS-BO, AS-RL, AS-E, AS-D, AS-VL, AS-BS, AS-OL, njll. Zingasetshenziswa futhi ukukhiqiza i-Light Fast Brilliant Red BBC, i-Light Fast Red BBN, i-Rubber Red LG, i-Pigment Brilliant Red 6B, i-Lithol Red BK. Zisetshenziswa futhi njengezithako zokudaya.
Ngemva kokuba i-β-naphthol kanye ne-sodium hydroxide zenze usawoti, ukushisa kanye nokunciphisa ukucindezeleka kuyaphela, kanti usawoti we-β-naphthol ongenamanzi otholakalayo ufakwa i-carboxylated ne-carbon dioxide ukuze kukhiqizwe usawoti we-2,3 acid disodium, ozobe usufakwa i-acid nge-sulfuric acid ukuze kutholakale umkhiqizo oqediwe.
